Express 0.00000008 using scientific notation: Use $10^{\wedge}$ format (i.e. $10^{\wedge} 2$ for 10 squared) $8 \times 10^{\wedge}-8$ $8 \times 10^{\wedge} 8$ $8 \times 10^{\wedge}-9$

Step 1 ：The scientific notation for a number is expressed as a number between 1 and 10 multiplied by a power of 10. In this case, the number is 0.00000008.

Step 2 ：To express this in scientific notation, we need to determine the power of 10 that will shift the decimal point to the right of the first non-zero digit.

Step 3 ：The power of 10 is -8 and the coefficient is 8.0.

Step 4 ：Therefore, the scientific notation of 0.00000008 is \(8.0 \times 10^{-8}\).

Step 5 ：Final Answer: \(\boxed{8.0 \times 10^{-8}}\)
